Abstract (en)
[origin: US4324246A] An article of manufacture is disclosed for absorbing liquids, particularly body exudates such as menstrual discharges. An apertured formed film topsheet having a layer of fibers affixed to the inner surface thereof overlays an intermediate layer having a multiplicity of tapered capillaries. The apertured formed film topsheet has a specified combination of caliper, percent open area and percent of apertures having an equivalent hydraulic diameter less than or equal to 0.025 inches (0.064 cm.) which impart a stain resistant character to the topsheet.
